DIFFERENTIABLE ANALYTICAL TEST STRIP AND TEST METER COMBINATION
First Claim
1. An analytical test strip and test meter combination for use in the determination of an analyte in a bodily fluid sample, the analytical test strip and test meter combination comprising:
- an analytical test strip with;
at least one electrode;
a first electrical contact pad in electrical communication with the electrode and configured to communicate an electrical response of the electrode to the test meter;
a second electrical contact pad in electrical communication with the electrode and configured to communicate an electrical response of the electrode to the test meter should the test meter be in electrical communication with the second electrical contact par, the second electrical contact pad having electrical continuity with the first electrical contact pad; and
a third electrical contact pad; and
a test meter with;
a test strip receiving module with at least a first electrical connector pin and a second electrical connector pin; and
a signal processing module,wherein;
the first electrical contact pad and the second electrical contact pad are integrated as a continuous electrical contact pad and disposed in either of a first predetermined spatial relationship to the third electrical contact pad and a second predetermined spatial relationship to the third electrical contact pad; and
the signal processing module is configured to distinguish the predetermined spatial relationship of the first electrical contact pad and the second electrical contact pad of an analytical test strip inserted into the test strip receiving module by sensing one of electrical continuity between the first electrical connector pin and the second electrical connector pin via the first electrical contact pad and second electrical contact pad and electrical discontinuity between the first electrical connector pin and the second electrical connector pin via the first electrical contact pad and, thereby, distinguish the inserted analytical test strip as having the first predetermined spatial relationship or the second predetermined spatial relationship.

Abstract
An analytical test strip (“ATS”) and test meter (“TM”) combination for use in the determination of an analyte in a bodily fluid sample includes an ATS and a TM, and a method for determination therewith. The ATS has an electrode, a first electrical contact pad in electrical communication with the electrode and configured to communicate its electrical response to the TM; a second electrical contact pad in electrical communication with the electrode and configured to communicate its electrical response to the TM should the TM be in electrical communication with the second electrical contact pad and a third electrical contact pad. The second electrical contact pad has electrical continuity with the first electrical contact pad and the first and second electrical contact pads are integrated as a unified electrical contact pad and disposed in either of first and second predetermined spatial relationships with respect to the third electrical contact pad.

12. A method for determining an analyte in a bodily fluid sample, the method comprising:
-
inserting an analytical test strip into a test strip receiving module of a test meter; sensing, using a signal processing module of the test meter, one of electrical continuity between a first electrical connector pin of the test strip receiving module and a second electrical connector pin of the test strip receiving module via a first electrical contact pad and a second electrical contact pad of the analytical test strip and electrical discontinuity between the first electrical connector pin and the second electrical connector pins via the first electrical contact pad wherein the first electrical contact pad and the second electrical contact pad are integrated as a continuous electrical contact pad; distinguishing, using the signal processing module, the inserted analytical test strip as having a first predetermined spatial relationship of the first electrical contact pad and the second electrical contact pad with respect to a third electrical contact of the inserted analytical test strip or a second predetermined spatial relationship of the first electrical contact pad and the second electrical contact pad with respect to a third electrical contact of the inserted analytical test strip; and ascertaining suitability of the analytical test strip based on the distinguishing step; and determining, based on analytical test strip suitability, an analyte in a bodily fluid sample applied to the analytical test strip. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
